Clariant completed 100 million Swiss franc ($123 million) investment in the Daya Bay facility in Longgang district in Shenzhen, Guangdong province, with the second production line becoming fully operational in November, the company announced on Wednesday.

This expanded capacity strengthens Clariant's ability to meet growing demand for more sustainable flame-retardant solutions in Asia and globally, particularly in the rapidly expanding e-mobility sector, it said.

"Our continued investment in the Daya Bay facility underscores our commitment to supporting the significant growth of engineering plastics applications in e-mobility and electrical & electronic segments," said Angela Cackovich, business president Adsorbents & Additives and EMEA and member of the Executive Steering Committee.

"With this world-class manufacturing plant, we strengthen our leading position in innovative and more sustainable fire safety solutions while improving our ability to serve customers across the Asia Pacific with reduced delivery times and tailored solutions."

Clariant also unveiled its newly expanded facilities on the same day at Daya Bay to better position itself to contribute to the health and wellbeing of Chinese consumers while supporting the growth of local industries with its innovative specialty chemical.

The Daya Bay facility now serves Clariant's healthcare business, maintaining consistent quality standards across China and worldwide.

In addition, Clariant announced the expansion of its Exolit OP flame retardant portfolio with two new high-performance solutions specifically designed for polybutylene terephthalate applications in e-mobility.

These innovations are particularly significant as the e-mobility industry transitions to higher voltage systems of 800 V and above, requiring materials with superior electrical insulation properties and long-term stability under demanding conditions, it said.
